ALE-DRAWING APPARATUS.

Specication of Letters Patent.

Patented Apr. 1d, 191e.

Application filed April 5, 1913. Serial No. 759,145.

To ZZ whom it may concern Be it known that I, HENRY SCHWARZ, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful improvements in Ale-Drawing Apparatus, of which the following is a speciication.

This invention relates to improvements in liquid dispensing apparatus and particularly to that class adapted to be used in connection with e'tfervescent liquids, such as fresh ale.

The lirst object of the invention is to provide means in such apparatus as will enable the surplusage of foam, caused by eX- posure of the liquid to the air, to be removed or restrained to such extent as may be desirable when a quantity of liquid is withdrawn.

A second object is to provide means that shall maint-ain the liquid free from possible pollution by insects, dust or even air, delivering the contents in its original purity and under a suitable pressure or head And finally, to provide such means in ornamental forms adapted for display, the operative parts being readily accessible and so arranged as to be practically indestructible.

These and other objects are attained by the novel construction and combination of parts hereinafter fully described and shown in the accompanying drawings, forming part of this specification, and in which Figure 1 is a perspective view of a complete installation of the apparatus showing its application. Fig. 2 is a sectional view of the faucet taken on line 22 of Fig. d. liig. 3 is a vertical transverse sectional view of the settling tank showing the operative parts within, and, F ig. 4 is a horizontal transverse sectional view of the faucet.

The form of apparatus chosen to illustrate the invention is that applicable to dispensing ale, in relatively small quantities in condition to be immediately consumed, in which the liquid is forced from its original package, as a barrel or keg, to the faucet under pressure of gases to which the ale is subjected.

As is well known, under ordinary conditions, fresh ale is in a state of effervescence to such an extent that a glass held under the faucet will be filled rapidly to a point of overflow with foam and very little actual liquid; therefore in order to provide a beverage that can be immediately quaft'ed, it is the usual custom to draw ale into any convenient receptacles prior to dispensing and in them let it stand and settle until the foamy condition has subsided; these receptacles are usually without covers, therefore unsanitary, uncleanly and serve to attract flies and other insects to which the contents are accessible; when it is desired to serve, a glass is partially filled with the settled ale, then held under the faucet to receive a further quantity and a desired proportion of foam and then passed over the bar. In order to relieve these described conditions and deliver the alc in proper proportions of liquid and foam, but entirely free from contamination of any kind, has been the main purpose of the present invention which 1s accomplished in the following manner: The barrel l() in which the ale is received rests horizontally on supports 11 in the basement or cellar' below the bar and is tapped at the end to receive a spigot or faucet 12 from which leads a pipe 13, up to a T 16 in one branch of which is a horizontally disposed pipe 17 leading to one of the faucet entrance openings Ll2 through a union 33. From the other opening in the T 16 is a branch pipe 1S having a valve 19 controlling the Vflow therein. The pipe 18 has an upturned portion extending through the lower head 29 of the settling chamber 2O to a point preferably above its center where it communicates with a faucet 21 operable from the side through a lever 22 which is kept in a normally closed position by means of the weight 23. A link 24C extends between the lever 22 and a depending member 25 attached to the head 26 of a bellows 27 disposed within and near the top of the settling chamber which is covered at its upper end with a tightly fitting cap or head 28. As indicated in the drawings the settling chamber 20 is formed to representaminiature barrel but may be made of any shape desired. An element 27 is secured at its lower edge by means of an internal ring 27 which holds the flexible material of which it is made, tightly against the interior walls of the chamber 2O so that neither air or liquid may pass through. The head 2S is made readily removable so that access therebelow may be easily obtained; at the same time this head furnishes a desirable finish to the chamber which prevents injury to the parts below, as well as to prevent the entrance of ing arranged immediately rearward of the faucet body which is provided with parallel slots 44 and 45 which terminate at the conical bored opening 46 in which is fitted the plug 47 adapted to be turned by the handle 4S so as to receive liquid from either of the openings in the branches and 41. The body of the faucet 35 is preferably `flanged as at 50 and. has a threaded portion 51 adapted to extend through suitable supports arranged below the bar, being clamped in position by means of the collar 52 threaded thereon and arranged oppositely to the flange 50. The members 40 and 41 approach each other at their inner ends, the surrounding body being bored to receive the extreme end of the faucet portion '51,sothat the openings properly register; a flange 53 is also formed with the inner end ofthe Y shaped faucet member adapted to be drawn tightly against the body member by means of the bolts 54 passing through both of the flanges 50 and 53 so that practically continuous passage-ways are secured through both parts of the faucet, which is finished with a spout 55 of the usual pattern. Y

In operation, the valves 12 and 19 being opened, the liquid is caused by the gaseous pressure to ascend the pipes and will enter the settling chamber 20 so long as the valve 21 is open. This valve however, is automatically closed when the air in the chamber 20 is compressed by means of the entering liquid to such an extent as to expand the bellows 27 thereby causing the valve 21 to close. It will be obvious however, that by opening the valve 30, the compressed air may escape, as desired, so that a greater quantity of liquid may enter within the chamber 20.

In order to be able to see at all times how vmuch liquid is in the chamber 2O a gage glass 31 is provided its upper end connecting with the air valve 3() while its lower end communicates with an elbow 32 entering the chamber 2O near its bottom, in such manner that the liquid in thc chamber flows freely into the glass tube, indicating the height of its contents.

'Io permit of access to the interior of the chamber for cleansing the same or any other purpose, an opening is made in the side walls and covered by the removable hand lated so that its opening is brought into reg-V ister with the slot 44 whereupon liquid is delivered direct through the pipe 13, thus any desired mixture may be obtained. It will furthermore be obvious that so long as the valves 12 and 19 be left open, that there will always be a quantity of liquid in the chamber 20 which is in conditionto be withdrawn.

I am aware that settling tanks for liquids are not new, but the arrangement of means within the chamber, whereby the quantity of liquid is controlled and delivered uncontaminated, in combination with liquid from the original package, and under the original initial pressure is believedvto be novel.

Therefore what I claim and desire to secure by Letters Patent, is: Y

1.V In a liquid dispensing apparatus, the combination with a liquid containing tank and an inlet pipe extending therein, of a yieldingly mounted false head hermetcally sealing said tank, a removable protective cover over said false head, a faucet on said inlet pipe, operative connections between said faucet and said false head anda weight adapted to keep said faucet normally open, all of said elements being contained within the body of said tank.

.2..In a liquid dispensing apparatus, the

tank body and an outlet pipe at the bottom thereof adapted to discharge the liquid contents of said tank by gravity.

In testimony whereof, I have hereunto signed my naine to'this specification lin the presence of two subscribing witnesses.
